GENERAL MORBIDITY IN THE 2008

OROYA

view based on information from the Ministry of Health of Peru, dominated by respiratory diseases in medical practice throughout the country, we are presenting the information in the pathology found in three different hospitals in La Oroya in 2008, as a first information, given that the national statistical information has a considerable delay.

1 .- ESSALUD, Social Security Hospital workers serving the area, their wives and children under 18. 2 .-

HEALTH CENTER OROYA, Centre Hospitalier Ministry of Health clinic, which caters to the population without health insurance and whose population is predominantly children, women and elderly. 3 .-

Chulec MEDICAL CENTER, Small Private Hospital Center Doe Run Company, which serves parents and children of workers who have no access to social security, some private insurance systems and case dependent on the Company.

This information will allow our readers an idea of \u200b\u200bthe epidemiological profile of an industrial town about 50 000 inhabitants, 3730 meters, located in the Peruvian Andes to 3 hours east of Lima, called La Oroya and that is also known as: "The Metal Capital of South America" \u200b\u200b for being one of the largest metallurgical centers of the world since 1922 .

At the same time will demystify some tissues paradigms speculate on the main disease in this city.

AFFINITY OF HEMOGLOBIN FOR OXYGEN AT THE HEIGHT

dissociation curve of hemoglobin

AFFINITY OF HEMOGLOBIN FOR OXYGEN AT THE HEIGHT IS DIMINISHED

want to add some ideas to read the previous article of this blog: " MAN IS THE HEIGHT FULLY ADAPTED? "we have sought to complement, so we extend some concepts and images that help us better understand the dissociation curve of hemoglobin.

Saturation is the percentage relationship between hemoglobin bound to oxygen or oxyhemoglobin (HbO2) and total hemoglobin. That is to say between the content O2 present in the blood and their potential to contain it.

hemoglobin and oxygen form to join a labile compound, oxyhemoglobin (HbO2). The physical and chemical characteristics of this union have not been properly interpreted, but their behavior in breathing is one of the most interesting and wonderful functional systems has created nature.



The amount of hemoglobin that binds oxygen in the blood is proportional to the pressure of O2. However, HbO2 and pO2 relationship is not linear but exponential curve that represents it is called DISSOCIATION CURVE OF HEMOGLOBIN.

Saturation is fully operational at pressures of 100 mm Hg, when the pressure decreases the oxygen is released. Early

Great Falls tension required to release small amounts of oxygen, as well as low pressure for example at 60 mm Hg saturation is still 90%. As you descend the relationship is reversed and the middle of the curve small changes in pressure sufficient to release large amounts of oxygen.

Hb binds oxygen for your call "affinity." As full saturation is on the horizontal part of the curve, it is very difficult to determine the pressure of O2 to get to 100% saturation and preferably Use the "value of pO2 is necessary for 50% saturation" to describe quantitatively the affinity.

height in the affinity of hemoglobin for oxygen is reduced to facilitate the acquisition of oxygen to the tissues . Benesh has shown that the oxygen affinity of hemoglobin can be reduced by their interaction with organic phosphates (2-3 DPG) in red blood cells. This can already see the 24 hours up to the task.

Saturation and Hemoglobin Level

Altitude Hypoxia increases organic phosphates contained in red blood cells that are responsible for the increase the use of oxygen to the tissues.

The physiological significance of this affinity is evident. The O2 Hb can release more easily and relatively higher pO2.

Other environmental conditions such as pH, temperature, pCO2 and 2-3 DPG can shift the dissociation curve of hemoglobin.
